A fastening tool having a socket and a socket wrench with laser induced friction surfaces or lines on the outer surface of the socket is described herein. The laser induced friction surfaces may have a plurality of kerfs with recast material to increase the coefficient of friction on the outer surface of the socket. As a result, the user of the fastening tool may pull the socket off a head of a fastener with his or her hands instead of having to dislodge the socket first with a blunt object, such as a hammer. It is contemplated that the socket wrench may have laser induced friction surfaces or lines also.

The present disclosure provides a residual stress measurement method and system for ceramic materials. The residual stress measurement method for ceramic materials comprises the following steps: polishing a target position by using a laser engraving machine; after polishing is completed, pasting a strain rosette at the target position, and connecting the pasted strain rosette with a strain collector; designing a target punching path according to a punching position of the strain rosette in a software terminal of the laser engraving machine; punching the ceramic materials to be measured according to the target punching path by using the laser engraving machine; after punching is completed, inputting collected strain data into a residual stress analysis terminal by a strain collector, and calculating and obtaining residual stress result data by the residual stress analysis terminal.

A firearm having a laser induced friction surface. A method for forming the laser induced friction surface on the firearm may includes the steps of disposing the laser machine adjacent to a component of the firearm, adjusting the laser machine, then applying the laser beam of the laser machine onto a component surface.

A method for controlling surface asperity during laser sealing of a membrane vent hole. The method includes applying a main pulse from a main laser to the membrane vent hole at a first time. The main pulse has a main pulse cross-sectional shape, a main pulse power profile, and a main pulse duration. The method further includes applying one or more supplemental pulses from one or more supplemental lasers to the membrane vent hole at a second time later than the first time. The one or more supplemental pulses have supplemental pulse cross-sectional shape(s), supplemental pulse power profile(s), and supplemental pulse duration(s). The first and second applying steps form a seal over the membrane vent hole. The seal includes a seal surface having a controlled surface asperity characteristic.

An example method includes providing a first semiconductor workpiece including a first portion and a second portion. The example method includes providing emission of one or more lasers through a thickness of the first semiconductor workpiece to remove the first portion of the first semiconductor workpiece from the second portion. In some implementations, the second portion has a shape corresponding to a second semiconductor workpiece of a different diameter relative to the first semiconductor workpiece.

A knife configured for use with an electrosurgical forceps having curved jaw members and a method of manufacturing the same. The knife includes a distal body having an inner side and an outer side, a first etching on the outer side of the distal body defining a distal cutting edge and a second etching on the outer side of the distal body extending along a portion of a length of the distal body to define relatively protruded and relatively recessed surfaces extending along a portion of the length of the distal body on the outer side thereof.

In a high voltage vehicle electronics system, laser welding may be used to connect components mechanically and electrically to bus bars. To overcome issues associated with the high reflectivity of materials commonly used for these applications, a laser-applied surface treatment is used on the components. The surface treatment alters several properties, including reflectivity, of the surface, improving the quality of the resulting weld.

When a laser beam is used to perform shape processing on an edge surface of a disk-shaped glass plate, in order to suppress strain (retardation values) in the main surface of the glass plate, the disk-shaped glass plate is floated above a base, and the edge surface of the glass plate is processed into a target shape by irradiating the edge surface with the laser beam while contactlessly heating the glass plate in a state where the glass plate is floated, and moving the laser beam relative to the edge surface in the circumferential direction of the disk-shaped glass plate.
